38-288-INK 12.5mm Dia. x 20mm FL; VIS 0deg; Inked; Plano-Convex Lens VIS 0° 425-675nm

The 38-288-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a circular base shape with a diameter of 12.5mm and a thickness of 1.4mm at the edge, transitioning to 3.5mm at the center. The effective focal length (EFL) is 20mm, and the front radius of curvature (R1) is 10.34mm. The back focal length (BFL) is 17.69mm, and the lens does not have an inner or outer radius.

The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The wavelength for this lens is 587.6nm. The lens features a VIS 0° coating on both the front and back, which is Edmund Optics' standard curve coating for visible light applications. This coating enhances the lens's performance by reducing reflection and increasing transmission.

The lens is in stock and available for purchase through the provided weblink. This detailed description should assist users in determining if this lens meets their specific optical needs.
